Use the equation to predict how many glasses with 9

cluponka [151]

Answer:

Bella can sell 13.78 glasses with 9 pieces of bling.

Step-by-step explanation:

Given the function

y=1.36x+1.54

As pieces of the bling are represented on the x-axis, and the number of glasses is represented on the y-axis.

Given that the number of pieces of bling = x = 9

Thus,

$y = 1.36x+1.54$

$= 1.36(9)+1.54$

$=12.24+1.54$

$=13.78$

Thus, Bella can sell 13.78 glasses with 9 pieces of bling.

Answer:

x =2, y = 2

Step-by-step explanation:

$x + 2y = 6....(1) \\ -x + 5y = 8....(2) \\ adding \: equations \: (1) \: and \: (2) \\ x + 2y = 6\\ -x + 5y = 8 \\ - - - - - - - \\ 7y = 14 \\ y = \frac{14}{7} \\ \huge \red{ \boxed{ y = 2}} \\ substituting \: y = 2 \: in \: equation \: (1) \\ x + 2 \times 2 = 6 \\ x + 4 = 6 \\ x = 6 - 4 \\\huge \purple{ \boxed{ x = 2}} \\ \\ \huge \orange{ \boxed{(x, \: y) = (2, \: 2)}}$

The Graduate Record Examination (GRE) is a test required for admission to many US graduate schools. Student’s scores on the quan

Dmitry_Shevchenko [17]

Answer with Step-by-step explanation:

Since we have given that

Mean = 150

Standard deviation = 8.8

An admissions officer at a large graduate school believes the mean is less than 150.

a)Determine the null and alternative hypotheses.

So, hypothesis :

$H_0:\mu =150\\\\H_a:\mu\neq 150$

b)Explain what it would mean to make a Type I Error.

As we know that Type 1 error are those errors in which null hypothesis is supposed to be rejected but not get rejected.

So, here, mean is not less than 150 but in actual it is less than 150.

c)Explain what it would mean to make a Type II Error.

As we know that Type II error are those errors in which null hypothesis is not supposed to be rejected but it gets rejected.

So, mean is less than 150 but actually it is not less than 150.
